Greenlink interconnector submits planning applications for onshore works in Wales

22 April 2020. In a major milestone for the proposed Greenlink electricity interconnector between Ireland and the UK, Greenlink Interconnector Limited has today submitted three planning applications for the project’s onshore works in Wales, including underground cable installation and construction of a converter station. The applications for planning permission have been submitted to Pembrokeshire County Council and Pembrokeshire Coast National Park Authority. This follows a period of consultation on the draft planning applications, which ran from 18 December 2019 to 22 January 2020. The final applications once validated will be subject to a further 21-day period of statutory public consultation to be undertaken by the relevant local planning authorities.

Nigel Beresford, CEO for Greenlink Interconnector Limited, commented;

“We are delighted to have reached this major project milestone and to be submitting our onshore planning application in Wales. It represents the culmination of over 3 years of detailed technical and environmental work by our team and valuable input from local stakeholders to produce an application that we believe is of the highest quality, balancing the need to protect sensitive and valued areas like Freshwater West beach whilst maximising the important local economic benefits.”

In Pembrokeshire the Greenlink interconnector comprises a subsea cable intended to come ashore under the beach and dunes at Freshwater West and continuing underground to a new converter station located near to the existing Pembroke substation.

Copies of the planning documents, including the application, plans and combined supporting documents, are published on for the following applications:

  • Pembrokeshire County Council Outline Planning Application: Proposed development of a Converter Station and upgraded permanent access road from Wallaston Cross to the Converter Station, plus associated landscaping, drainage and other supporting infrastructure associated with the development at land to the south of Pembroke Power Station.

  • Pembrokeshire County Council Full Planning Application: Proposed development ofunderground HVDC and HVAC cables and associated works extending from the boundary with PCNPA at Neath Farm to land immediately south of the National Grid substation at Pembroke Power Station.

  • Pembrokeshire Coast National Park Authority Full Planning Application: Proposed installation of two permanent underground HVDC cables, one permanent fibre optic cable, a temporary landfall HDD compound and a series of temporary construction haul roads extending from the landfall site at Freshwater West to the boundary with Pembrokeshire County Council at Neath Farm.

Anyone who wishes to make representations to the Local Planning Authorities during the public consultation period should go to and Tom Brinicombe, who leads planning and development for the project in Wales, added;

“I firmly believe that our final proposals have really benefited from the input we’ve received from the community and other stakeholders. One of the major concerns raised has been any potential impact on Freshwater West. We have taken these concerns very seriously and committed to drilling under the beach to avoid direct impacts on beach users. Additionally, we will schedule work to minimise local impacts. “Due to Coronavirus and the latest UK Government advice, we are unable to hold public consultation events or face-to-face meetings with stakeholders. However, local people and organisations with an interest in the project will be able to view and make comments on the applications online or by post and we will also have all documents available on the Greenlink website. I and other Greenlink representatives remain available to answer any questions about the project by email and telephone and I would encourage people to get in touch if they have any queries or feedback.”

Greenlink is one of Europe’s most important energy infrastructure projects. The electricity interconnector brings benefits on both sides of the Irish Sea for energy security, regional investment, jobs and the cost-effective integration of low carbon energy.

The marine planning applications in both Wales and Ireland were submitted towards the end of 2019 and the application for onshore works in Ireland is currently being prepared. The project is expected to have a three-year construction programme, offering local supply chain opportunities.
